I read the fact and I think the guide lines to choose a contractor are pretty simple.
I think there are few things that are fundamental when contracting someone...
- Check with your friends and family to see if they know about this contractor... Look for feedback about their work and professionalism.
- Check if you need a permit or not to do get the work done.
- Sign a contract. This way the work will get done under the law and it is easier to take care of legal matters.
